## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Changes things (4)

Creates or changes something that can be changed back. Claude Code: ask.

### `big_moves`

- The name "big_moves" says "move": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
PRO. Alert list: liquid perps that moved more than a threshold (default 10%) in 24h, with funding context.
```

### `funding_extremes`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
PRO. Most positive and most negative funding rates across liquid perps (crowded longs/shorts), with annualised APR.
```

### `market_pulse`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
FREE. Snapshot of the top coins' perpetual futures: price, 24h change, funding rate (+APR), open interest; plus the top 3 24h movers among liquid perps.
```

### `perp_scanner`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
PRO. Full scanner across all USDT perpetuals: sort by change, volume, funding or open interest; filter by min 24h volume.
```

- **warn** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 4 tools that change things (4 write). Whether a call also works without credentials was not tested: tools are never called.

https://trading-data-mcp.donniertf.workers.dev/mcp: tools/list returned 4 tools to an anonymous client, including market_pulse (write), perp_scanner (write), funding_extremes (write), big_moves (write)
